About a year and a half ago I purchased 2 Raspberry Pis/XBMC for use un my home. The performance is deteriorating and I would like to upgrade to KODI. I'm fair computer user but that's all and my tech support has left town. I've found online that you you can purchase pre-recorded sd cards that claim to be plug and play. If true that should easily solve my performance and upgrade problems. My problem is that besides being 1 1/2 years old I don't know what model I have. One of the vendors I'm looking at says he has cards for Models B+, B, A+,A and 2B. You have a sticky " Pictorial Buying Guide for A, B and B+" that should help me identify my Pi. You show Models B+,B and A+ but mine appears to be one of the "older A or B models". One giveaway seems to be that I have connectors on all 4 sides whereas the "newer" ones seem to use only 3 sides.

Can someone help me identify my PI and perhaps tell me if any of these cards can be used in my Pi's.

There is a table somewhere that tells what each possible number means (i.e., to which model of Pi it corresponds). I have no idea where that table is stored (presumably somewhere under www.raspberrypi.org).

If it's 18 months old and has an ethernet port, then it's almost certainly a B.
PI2 launched ~Feb 2015
A+ ~Nov 2014
B+ ~Jul 2014

Original Raspberry Pi Model B's (either 256MB or 512MB models, that's the major revision change) will definitely work with a micro-SD card too using an SD adapter card, such as this.

if a vendor has cards for a B, why would the anyone go to the bother (and expense) of buying the 'wrong' card and an adapter?
Just because 'something' can be done, doesn't mean it should be.

For one thing...the full sized SD card used in the original Model B (and the A, for that matter) stick out quite a bit. People have damaged the card holder by dropping the board with the card in place. If you use a micro-SD card adapter, you don't run that risk. Alternatively...most micro-SD cards come with a full sized adapter and that way you can use the same micro-SD card in either a Model B or a B+ or Pi2B.

So...there are some good reasons to use adapters.

The pros and cons of such are way off topic. Let's stick to basics for the OP and get a card that fits and works.

The question now is what revision of B. There were a few important changes between the Rev 1 and later B models. Mostly the early ones had 256MB of RAM and USB current limiting fuses. The next models bypassed or got rid of those fuses. Then you got 512MB of RAM, and then the additional 8 pin GPIO connector holes.
